WIRING FOR MUTE INPUT
The back panel of the AD-4 has a 3.5mm non-shorting stereo connector
input labeled “Mute”. This is designed to be used with the PDM-1 Phone-
Doorbell-Mute module. When the PDM-1 is connected, the system will
temporarily mute when the phone or doorbell rings.
Doorbell
The back of PDM-1 will accept up to two AC or DC voltages from two
different doorbell chimes. This connection is done with two conductor wire
from the terminals on the doorbell chime to the Doorbell A or Doorbell
B inputs on the back of the PDM-1, Polarity is not important for this
connection.
Telephone Paging
The ring voltage from a phone line will trigger the AD-4 system to mute.
